Letters Patent'No. 98,879, (la-ted J amtary 18, 1876.

, ILLUMINA'IOR FOR srov'ss.

The Schedule referred to in these Letters Patentand'making part of the same.

To all whom it may concern;

Beit known-that I, BEX AM'IN Now, of the city of Albany, in the county of Albany, and 1n the State of New York, have invented an Improvement in Illuminators for Stoves, Furnaces, &c.; declare that the following is a full, clear, and exact description thereof, reference being bad to the annexed drawings, making part of this specification, in which- Figure 1 represents a front view of the illuminator, encased in a suitable frame on the rear of a stovedoor. 1

- Figure 2 is a horizontal section .on linea; x, of fig. 1. I Figure dis a perspective view of the illnminator detached.

The same letters are used in all the figures, in the designation of identical parts.

The object of my invent-ion is to so arrange an illuminator, for which Iobtained Letters Patent on N ovember 10, 1868, upon the door of a stove, or upon the stove itself, that it can be removed at any time with the greatest facility, when it becomesnecessary to do so, for the purpose of cleaning the glass tubes.

To this end, my invention consists in the construction of the illuminator, and in its combination with the door of a stove, as will be more fully explained hereinafter.

1n the annexed drawings-- A represents a stove-door, having a l. rge opening in its face, which is to be'closed by the illuminaton.

Upon the sides of this door are formed angular flanges a a, and upon that portion of these flanges which is parallel to the face' of the door, are fastened, or they may be cast in one piece with such door, strips a a, projecting inwardly, over the corners of the flanges, sufliciently to retain the illuminator.

Orossbars a a are stretched from one flange to the other, above and below the opening in the door, to strengthen them, as well as to serve as further security for retaining the illumiuator.

The lower cross-bar is united to the door by short bars, a, upon which the under edge of the illuminator rests, when inserted .in the door.

13 represents the illnminator, which is constructed of a number .of glass tubes, inserted in a suitable frame, of such size as to fitlooselyin the casing formed upon the rear side of the stove-door.

and I do hereby The upper end of the illuminator-fiame B, is' left open, for the convenient removal and insertion of the glass tubes, and in the other end, upon which the tubes rest, a long slot is formed, so as to allow a current of airto pass constantly through thetubes. The sides maybe provided with slots, in asimilar manner, as shown.

B are strips of wire gauze, inserted. between the end tubes of the illnminator and its frame, and under the ends of the tubes to prevent the gaseous products of combustion entering such tubes, and thus smoking them on the inside.

A short projection or ear, I), is formed on the upper end of the illnminator, by which to take hold with the hand, on iusertingor removing the same. In figs. l and 2, I have shown the illuminator, inserted in its place in the door. Should the glass tubes at any time become smoked so as to impair their translncency, the illuminator is removed out of the door, the opening of which may at such time be temporarily closed by a sheet of tin, and the tubes taken out of the frame, if necessary, and cleaned. This may be done while the stove is in' full operation.

I have described the illnminator as applied to a stove-door; but it is apparent, that it is equally applicable to doors of all other kinds of beating-apparatus, or that itmay be applied in any other part of V the stove or other heating-apparatus.

What I claim as new, and desire to secure by Let ters Patent, 'isv 1. In combination with a stove or other heating-appamtus, an illuminator, when such illumiuator is detacha-l'lly arranged thereon, substantially as and for the purpose set forth.

2; The combination of a stove-door, A, with the illuminator B, when arranged with reference to each other, substantially 'as and for the purpose set forth.

3. In combination with the glass tubes of the illuminator B, the wire gauze 15*, substantially as and for the purpose set forth.

, The above specification, signed by me, this 8th day of December, 1869.
